Java Memory Consumption and Server Unresponsiveness

in Database 5 comments

Hi team,

We have an OCI Compute instance running the OIC Connectivity Agent as a Java process, with an initial heap allocation of 2 GB.

Recently, the server became unresponsive, and we were unable to connect to it. We raised an Oracle SR, and Oracle confirmed that a Java process had consumed most of the available memory, triggering the Linux OOM Killer. They also mentioned that there was no infrastructure-related issue.

We performed a stop and start of the Compute instance, after which the server became accessible again.

  1. How can we prevent the Java process from consuming excessive memory and making the server unresponsive?
